That was really good.
Maybe it tried a little too hard to be 2001. Especially towards the ending, but it's an incredibly well made movie. With incredibly accurate (or at least plausible) science that you rarely ever see in SciFi like this. Brilliantly acted. Well worth watching in IMAX, I assume (which I didn't) . with the modern day topics that desperately need to be tackled of anti science bias and conspiracy idiots taking over.
I give it three out of three Potentially Inhabitable Planets!
